Can anyone identify this?
« on: 27 Jul 2007 at 11:53 »
Hello, i know this is not a bike but it's a start.

I have recently been given these 2 engines that are mounted on to some sort of frame. They are the beginnings of my first classic motorbike restoration project. I have been told that they are 1940s Douglas engines. I would be grateful if anyone could give my any information about the engines as I do not know anything about them! I would especially like to know which parts are original, and where I can source original parts.
A serial number I found on the engine is LAC 113, if that helps


thanks



Thanks for info, I have search the whole crankcase for numbers. Sadly, i could not find a number with the prefixes suggested, i will continue to look. As requested here are some pictures from different angles. I have replaced on the engine what i think could be the engine driven generator.

One of their industrial stationary engines, late forties or fifties timeframe I think, but I have not had a chance to look up the prefix yet.

Not exactly sure, but from information I was given many years ago it could well be as Doug says, an engine from 1940-50. Douglas by all accounts produced a series of side valve horizontally opposed twin industrial stationary engines during this period. The information I have gives the following capacities they were produced in namely, 248cc, 463cc, 543cc and 982cc. The engine numbers were prefixed  as VS25, VS45, VS55 and VS98 respectively. These numbers would I think be stamped on the lower parts of the crankcase. Never seen an engine as in the photo actually 'in the flesh'. Would be interested in photos taken from all round the engine. At the same time, other engines were produced, with the 348cc ohv air cooled engine ultimately developed into the power unit for the post war motorcycles. These particular engines were also produced in sizes other than 348cc although they were all side valve engines. They were 804cc and 995cc. Together with the 348cc they were prefixed by FT35, FT80 air cooled, FT80W (a water cooled version), FT80M again water cooled with synchromesh gear. Forward 2:1 and reverse 2.14:1. An engine driven generator is fitted and electric starting may be provided. What the set up here is I have no idea. The FT100 was the 995cc s.v air cooled and the FT100W was the 995cc s.v. water cooled version. Apart from this information that was passed on by an ex Douglas employee who worked as a draughtsman at Bristol Aeroplane Company, I have never seen any other information to back this up but there is nothing to doubt the authenticity of what he says. But, someone out there may know differently.....!!!!

Hello all
Thanks to ebay, I think I may have found an identical engine.
PETTER PU8 Stationary engine
There is no technical details, only make and model.
There are other pictures which can be found at

http://cgi.ebay.co.uk/PETTER-PU-8-STATIONARY-ENGINE-FOR-SPARES_W0QQitemZ220371746706QQcmdZViewItemQQptZUK_BOI_FarmingEquipment_RL?hash=item220371746706&_trksid=p3286.c0.m14&_trkparms=72%3A1688%7C66%3A4%7C65%3A12%7C39%3A1%7C240%3A1318

Although it still has 4 or 5 days to go, no one has bid on it yet
I hope this may help
Regards          Martin

Martin,

Looks pretty clear it is the same type engine. Not a Douglas at all but a Petter!
